Are Radion Wireless and B Series Keypads compatible with D7412Gv4/ D9412Gv4/ D7212GV4 Control Panels?
Radion Wireless and B Series Keypads are only compatible with D7412GV4 and D9412GV4 on firmware ver 2.0 or newer panels.
D7412Gv4 or D9412Gv4 ver 1.0 can be upgraded to ver 2.0, however older SDI keypads will lose most of their functionality as part of the upgrade
The D7212GV4 CANNOT be upgraded. Hence it will never be compatible with either of those devices.
